Initially recorded in Colorado in 2003 as 'Untitled,' Bathymetry is Cities Of Earth's first proper recording. Using no computers, the music was assembled by CD-bouncing between different recording sources, with material culled from hours of sound collages and television & radio treatments. Second-hand synths, samplers and effects hardware provided musical and rhythmic elements. Bathymetry is 8 unnamed tracks, listed simply as Bathymetry 1 - Bathymetry 8.
Like its namesake, the album is a thematic exploration of unseen, submerged topographies; murky depths and scattered waves of light below the surface. More ambient than some later work, Bathymetry possesses more of a dreamlike temperament, and remains one of COE's favorite releases. Although other music was recorded earlier, this album is granted the title of 'first proper recording,' as it introduced many of Cities Of Earth's distinctive early sonic habits and techniques: hazy & psychedelic arrangements, complex sound collage, recursive sampling, found sound, and 'chewy' rhythms. Bathymetry also marks the only Cities Of Earth song to feature sung vocals (on 'Bathymetry 5'...albeit very quietly and through a vocoder). Lastly, to commemorate the web-publishing of this album, it's been given new artwork.
